Abstract
A light emitter includes: plural light emitting thyristors that each have an anode, a cathode, and a gate and are connected in parallel between a reference voltage line to which a reference voltage is supplied and a lighting voltage line to which a lighting start voltage for starting lighting is supplied, in which the anode and the cathode are connected respectively to the reference voltage line and the lighting voltage line; and a gate voltage setting section that, when at least one of the plural light emitting thyristors transitions from an off-state to an on-state, sets a voltage on the gate of each of the plural light emitting thyristors to a voltage between the lighting start voltage and an on-state voltage of the light emitting thyristor.
